Abstract
An integrally molded plastic lubricant fitting which has the check valve at the outlet of the fitting instead of at the inlet, and where hydrostatic pressure from the lubricant within the body of the fitting maintains the fitting in an operative position. The latter is further assured through the provision of circumferential ribs on the outer surface of the body of the fitting, such coacting with the inner surface of a predrilled fitting hole in a positive manner.
Claims3
A unitary semi-rigid lubricant fitting for a drilled hole comprising a body having a longitudinal passageway therethrough, said passageway defined by an inlet end and an outlet end, a check valve disposed at said outlet end, and said inlet end adapted to extend from said drilled hole when fitted therein and further adapted to receive pressurized lubricant from a lubricant gun, whereby the hydrostatic pressure of lubricant injected from said lubricant gun balloons said body into a gripping relationship within said drilled hole, locking said fitting against outward movement from said drilled hole.
